A resale certificate's life depends on the state. Ten states in our review put an expiration or mandatory renewal on the certificate, 30 let it run until the buyer revokes it or purchases stop, and six publish no clear rule. If you accept a certificate that has lapsed, the state can treat the sale as taxable and bill you for the tax, so check the date before you rely on one.
This guide covers 45 states and Washington, DC. We checked each against the state tax agency's own guidance on September 26, 2026. This is educational information, not tax advice. Rules change, so confirm the current rule with the state before you rely on it.
Which states put an expiration on resale certificates?
| State | How long the certificate lasts |
|---|---|
| Arizona | The buyer picks a single transaction or a date range. The agency encourages periods of 12 months or less. A seller can rely on one in good faith for up to 48 months only with documentation that the buyer's license was valid for each year covered |
| Connecticut | A blanket certificate must be renewed at least every three years from its issue date |
| District of Columbia | Valid for one year with an expiration date, renewed each year through MyTax.DC.gov. Accepting an expired certificate is treated as bad faith |
| Florida | Annual resale certificates expire every December 31. A seller may rely on a certificate past its expiration for customers who buy on account at least once every 12 months |
| Illinois | No statutory expiration, but the department says blanket certificates must be updated at least every three years, and sooner if the stated resale percentage changes |
| Louisiana | Valid for one year from approval and renews automatically 60 days before expiration if sales activity and payments are timely |
| Maine | Expires on December 31. A new certificate runs through that year plus three more calendar years, and a renewed one is valid for five calendar years |
| Michigan | A blanket certificate can carry an expiration date of up to four years, and defaults to four years unless a shorter period is stated |
| Oklahoma | Later purchases need no new certification until the buyer's sales tax permit expires. Otherwise the renewal interval defaults to three years |
| Washington | Reseller permits are generally valid for four years, and two years for contractors, new businesses and businesses with reporting problems |
Which states let resale certificates run until revoked?
These states set no fixed expiration, but many attach a 12-month rule. The certificate keeps working while the buyer and seller keep trading, and lapses if more than 12 months pass without a purchase between them.
No fixed expiration, with a 12-month gap rule: Arkansas, Iowa, Kansas, North Carolina, North Dakota, Nebraska, New Jersey, South Dakota, Utah, West Virginia.
No fixed expiration, valid until revoked or the buyer's circumstances change: California, Colorado, Georgia, Hawaii, Kentucky, Maryland, Minnesota, Missouri, New Mexico, Nevada, New York, Ohio, Rhode Island, South Carolina, Tennessee, Texas, Virginia, Vermont, Wisconsin, Wyoming.
Some of these states still recommend updating certificates every few years. For example, South Dakota suggests every three to four years and New Jersey every four. A recommendation is not a requirement, but a fresh certificate is cheap insurance in an audit.
Which states do not publish a clear rule?
Alabama, Idaho, Indiana, Massachusetts, Mississippi, Pennsylvania. We found no official guidance on expiration or renewal for these states, or, in Mississippi's case, there is no resale certificate to expire because the seller documents each sale with the buyer's permit number. Treat the certificate as needing a periodic refresh, and ask the state if you rely on one.
What should a seller do about expiration?
- Record the issue date and any expiration date when you collect a certificate.
- Re-collect a certificate before it lapses in the ten expiring states, and more often if the buyer's circumstances change.
- Watch for the 12-month gap: a buyer who stops buying for a year may need a new certificate before the next sale.
- Check that the buyer's permit is still active. In several states a certificate is only as good as the permit behind it.
- Keep certificates for as long as the state's audit window, since the state can ask for them years later.

Frequently asked questions
Do resale certificates expire?
In some states. Ten states in our review set an expiration or required renewal. Most others let a certificate run until the buyer revokes it, with a rule that it lapses after 12 months without a purchase.
How long is a resale certificate valid?
It ranges from one year (DC and Louisiana) to four or five years (Washington, Michigan, Maine), or indefinitely in states such as California and Texas.
What happens if I accept an expired resale certificate?
The state may treat the sale as taxable and hold you liable for the uncollected tax. DC treats accepting an expired certificate as bad faith.
What is a blanket resale certificate?
A certificate that covers repeated purchases from one seller, as opposed to a single-purchase certificate. Many states let a blanket certificate run until revoked, subject to a 12-month gap rule.
Does a resale certificate from one state work in another?
Sometimes. Many states accept the Multistate Tax Commission uniform certificate, and some accept home-state certificates from out-of-state buyers. See our guide to out-of-state resale certificates.
